Mont Terri Project

The Mont Terri Project is an international research project for the hydrogeological, geochemical and geotechnical characterisation of a clay formation (Opalinus Clay).

As the representative of the federal government, swisstopo concluded contracts with the project partners and with the Canton of Jura, providing a legal basis for the activities.

The federal government represented by swisstopo funds the operation of the rock laboratory (no third party is involved). The participating partners fund the research programme.

We give here the history of the project from the mid-1990s onwards with a summary of the milestones.
